assembled, which will be strong enough to' have a long life and maintain its resiliency, and which will keep the last parts in their enpanded or collapsed position.

it is my object to provide a novel form ot resilient link to be used either with or without resilient pins.

lt is a 'further object to so arrange the mounting of this link that a line drawn between the centers of the points of attachment ot the links to the last parts will pass over Vthe center about which the last parts move when the parts are moved from expanded to collapsed position or vice-versa.

Referring to the drawings:

Figure 1 is a section through the last when it is in its expanded position.

Figure 2 is a section through the last in its contracted position.

Figure 3 is a section on the line 5-5 of Figure 1, showing the mounting ot the links on resilient pins.

Referring to the drawings in detail;

1 is the heel part of the last and 2 is the toe part. The heel part 1 has its upper tace 3 which adjoins the tace 4l ot the toe part ot the last at an angle to the vertical. rlhis tace 3 terminates in a semicircular projection 5 which is. received in a semicircularv depression 6 in the toe part of the last, so that a knuckle joint is formed between the parts. rlhe parts are limited in their move ment in one direction by the abutting surfaces 7 and are limited in their movement in the other direction by the abutting sur Jfaces 3 and il.

Each last halt is provided with the respective adjacentcutaway portions 8 and 9 in which are located the t-shaped links 10. These links are mounted upon the respective pins 11 and 12 and are made of some resilient material. The last halves are cut away as lat 1d and'lt to permit the lexing of these pins, Vuponwhich arefmounted the links. lt is also possible'to use my special ;orm of Vlinkvwith pins which are not resilient. l Y I y I lt will be lnoted that the last parts are adapted to move aboutthe center 15. This center 15 in Figureil is above a line drawn between the centers of the pins 11and 12 and below that line in Figure 2.'

The V -shaped links are composed of a pair ot arms, theends of which are riveted to one another at 16. The movement of the last parts over dead center will tend to spring the pins and also draw the arms of the links towards one `another so that thecenters of the connection 16 will approach one another when this passage over dead center is made.

rlhe pivotal point'indicated on the drawings is only approximate, but it is accurate suiiiccntly to illustrate the principle of construction, as the drawings are not drawn to scale. The fundamental idea is to have the line drawn between the centers of the points of attachment pass over thel dead .center which in a senseis the equivalent of the pivotal point. l

l desire to comprehend within my invention such modilicationsas may be necessary to adapt it to varying conditions.

Havingv thus fully` described myvr invention, what claim as new and desire to secure by vLetters Patent, is:

1. ln combination in a last, a heel part, a' toe;part, a link connecting said parts consisting of spaced members joined at the ends thereonand means for attaching said link to the respective parts,jsaid link being adapted upon movement of the last parte in the collapsing or expanding operation to permit its spacedmembers to approach each other.

2. ln combination in a last, a toe part, a heel part, said parts being adapted to rock on one another, a connecting means connecting said parts to one another having its central portions spaced from one another and its ends united, and an attaching means for said connecting means located in each part, said attaching means being adapted to be flexed upon the movement of the parts.
